Transmission zero engineering in lateral double-barrier resonant tunneling devices
نویسندگان
چکیده
Transmission zero engineering in lateral double-barrier resonant tunneling devices is investigated. We show that, by inserting a resonant cavity in the quantum well region of a lateral double-barrier resonant tunneling structure and engineering the placement of transmission zero-pole pairs, the current peak-to-valley ratio of the device can be drastically improved at low temperature. An advantage of this structure also is that a lower peak voltage can be obtained compared to the corresponding lateral double-barrier resonant tunneling device. © 1996 American Institute of Physics. @S0003-6951~96!01615-4#

Impact of Silicon Wafer Orientation on the Performance of Metal Source/Drain MOSFET in Nanoscale Regime: a Numerical Study
A comprehensive study of Schottky barrier MOSFET (SBMOSFET) scaling issue is performed to determine the role of wafer orientation and structural parameters on the performance of this device within Non-equilibrium Green's Function formalism. Quantum confinement increases the effective Schottky barrier height (SBH). (100) orientation provides lower effective Schottky barrier height in compa...
متن کاملVertical transport in graphene-hexagonal boron nitride heterostructure devices
Research in graphene-based electronics is recently focusing on devices based on vertical heterostructures of two-dimensional materials. Here we use density functional theory and multiscale simulations to investigate the tunneling properties of single- and double-barrier structures with graphene and few-layer hexagonal boron nitride (h-BN) or hexagonal boron carbon nitride (h-BC2N). We find that...
متن کاملMesopiezoresistive effects in double-barrier resonant tunneling structures
This letter reports a mesopiezoresistive effect in a double-barrier resonant tunneling DBRT structure. In a DBRT system, an external mechanical stress causes a tensile strain, and the strain, in turn, affects the resonant tunneling and thereby the resistance. Theoretical analysis was carried out on an AlAs /GaAs /AlAs DBRT structure under in-plane uniaxial tensile stresses. The results show tha...
متن کاملCoherent-electron intrinsic multistability in a double-barrier tunneling diode
Recently, a new mechanism leading to electrical multistability in coherent-electron tunneling devices was proposed. The reflection of coherent electrons at a barrier leads to the formation of resonant states in a quantum well in front of the barrier, and the resulting strongly modulated local density of states allows for multiple stable solutions of the Poisson equation to exist at fixed bias. ...
متن کاملNonlinear feedback oscillations in resonant tunneling through double barriers.
We analyze the dynamical evolution of the resonant tunneling of an ensemble of electrons through a double barrier in the presence of the self-consistent potential created by the charge accumulation in the well. The intrinsic nonlinearity of the transmission process is shown to lead to oscillations of the stored charge and of the transmitted and reflected fluxes. The dependence on the electrosta...
